Czech President Vaclav Havel was sworn in for his final five-year term at Prague Castle yesterday in an atmosphere far removed from the heady days of 1989 when he first rose to power.Havel (61), who struggled to capture enough votes in parliament last week to win a second term as Czech president, took the oath of office during a ceremonial session in the Gothic Vladislav Hall, from where Bohemian kings ruled for centuries.Under the Czech constitution, adopted when Czechoslovakia split in 1993, this must be Havel's last term in the post which has a strongly ceremonial character.Pope John Paul II met Iranian Foreign Minister Kamal Kharrazi yesterday in the first visit to the Holy See by a senior Iranian government official since the election of President Mohammad Khatami.The 77-year-old pontiff and Kharrazi discussed problems in the Middle East peace process, senior Vatican spokesman Joaquin Navarro Valls said, without giving further details.Kharrazi was believed to have delivered a message to the Pope from Khatami, a moderate who came to power after a surprise election victory last May. The Vatican has in the past called for religious freedom in Iran, citing problems encountered by some Iranians wanting to convert to Christianity.Titanic is on course to become the first billion-dollar film as it continues to top US box office charts. The most expensive movie ever made became the seventh biggest grossing film in history at the weekend, passing Independence Day. David Davis, an analyst with a Los Angeles investment bank, said: "It's likely to be the first ever to gross a billion dollars in worldwide box-office receipts." He told the showbusiness newspaper Variety: "It's remarkable how well it has held up." Titanic, which cost £121 million to make, has now topped the box office charts in the US for seven weeks and in 45 days has taken £187 million. The Spice Girls' much criticised Spice World film has earned more than £11 million in 10 days.
